This technology has been studied by aviation science and technology experts for many years, and the chainless bicycle has the following advantages: high speed (45km/h); Reasonable structure, safety and labor saving, good shock absorption and braking; The service life is longer than that of chain car, and it is not easy to be damaged; Light weight; No pollution. The production cost of chainless bicycles is about 3 yuan.
Chain-free labor-saving bicycle transmission device is the latest patented technology in the field of bicycle transmission. The technical contents are as follows: a, the center of gravity shifts to reduce friction and resistance; B, gear displacement, lengthening the lever length is labor-saving; C, closed transmission dustproof to prolong life; D, change the angle and increase the inertia.
The transmission device cancels the chain transmission system in structure, and is composed of internal gear, planetary gear, bevel gear and transmission rod, which improves the safety and reliability of the transmission system. It has been five years since the trial ride in 1997, and it has been proved that this transmission device is durable; Secondly, the trouble of chain dropping and oil rubbing on skirt pants is avoided, and the riding is fast and stable, especially for climbing, headwind, long distance and heavy load, which shows the mechanical performance of saving labor and power. Third, the output torque is 2% larger than that of bicycles with chains in the same building.
this transmission device is mainly used for bicycle series products.
There is another patented project-chainless labor-saving bicycle, which is the result of new technology research, and has achieved the design goals of innovation, practicality, novelty, beauty, flexibility, high efficiency, simple maintenance, labor-saving and power-saving. As confirmed by patent technology search, there is no such product filed in China, which is the first in China and there is no similar product abroad.
this patented product has laid a high-tech foundation for the product replacement in the 21st world bicycle market, which will certainly promote the reform and innovation of the bicycle market and the transformation of traditional device styles.
